PG::Error: ERROR: out of memory on Heroku

Question

I deployed an application on Heroku. I'm using the free service.

Quite frequently, I get the following error.

PG::Error: ERROR:  out of memory

If I refresh the browser, it's ok. But then, it happens again randomly.

Why does this happen?

Thanks.

Answer 1

If you experience these when running queries, your queries are complicated or inefficient. The free tier has no cache, so you're already out there.

If you're getting these errors otherwise, open a support ticket at https://help.heroku.com

heroku restart simply helped me though
